The Metric System

1. The Metric System

2. Our Learning Goal: • The student will be able to accurately measure distance, mass, and volume using the metric system.

3. What do you already know about the metric system? • Talk at your table and be ready to report out your knowledge!

4. What we already know:

5. The Metric System • A standard unit of measurement used throughout the world that is “based on the 10’s”

6. PREFIXES: • What do you already know? • Did your elementary teacher(s) teach you a phrase to remember the metric prefixes? • Talk at your table and be ready to report out!

7. PREFIXES: What we know:

8. PREFIXES: KiloHectodecaBASEdecicentimilli UNIT (meter, liter, gram) Largest Prefix Basic Prefix (m, L, g) Smallest Prefix

9. How do I use this? Largest Objects Average Objects Tiny Objects KiloHectodecaBASEdecicentimilli UNIT .001 km = .01hm = .1 dam = 1.0 m = 10 dm = 100 cm = 1,000mm **Based on ten! You are multiplying or dividing by 10! Simply move the decimal point left or right!** You need to consider: # of decimal places? Direction?

10. Examples: 753 grams = ______________ kilograms 4.72 meters = _____________ centimeters 34.6 decagrams = ____________ decigrams .562 hectoliters = ______________ milliliters 1,389.5 decimeters = ____________ hectometers 48.3 decameters = ______________ decimeters

11. Examples: 753 grams = .753 kilograms 4.72 meters = _____________ centimeters 34.6 decagrams = ____________ decigrams .562 hectoliters = ______________ milliliters 1,389.5 decimeters = ____________ hectometers 48.3 decameters = ______________ decimeters

12. Examples: 753 grams = .753 kilograms 4.72 meters = 472 centimeters 34.6 decagrams = ____________ decigrams .562 hectoliters = ______________ milliliters 1,389.5 decimeters = ____________ hectometers 48.3 decameters = ______________ decimeters

13. Examples: 753 grams = .753 kilograms 4.72 meters = 472 centimeters 34.6 decagrams = 3,460 decigrams .562 hectoliters = ______________ milliliters 1,389.5 decimeters = ____________ hectometers 48.3 decameters = ______________ decimeters

14. Examples: 753 grams = .753 kilograms 4.72 meters = 472 centimeters 34.6 decagrams = 3,460 decigrams .562 hectoliters = 56,200 milliliters 1,389.5 decimeters = ____________ hectometers 48.3 decameters = ______________ decimeters

15. Examples: 753 grams = .753 kilograms 4.72 meters = 472 centimeters 34.6 decagrams = 3,460 decigrams .562 hectoliters = 56,200 milliliters 1,389.5 decimeters = 1.3895 hectometers 48.3 decameters = ______________ decimeters

16. Examples: 753 grams = .753 kilograms 4.72 meters = 472 centimeters 34.6 decagrams = 3,460 decigrams .562 hectoliters = 56,200 milliliters 1,389.5 decimeters = 1.3895 hectometers 48.3 decameters = 4,830 decimeters

17. You Try: Which unit would you use to measure each of these objects? Why? (Use only the common prefixes discussed earlier: Kilo, base unit, centi, and milli)

18. Rate Your Learning on Today’s Lesson! 4 = In addition to score 3, you can help teach your peers 3 = you can accurately name the metric prefixes, convert between the metric prefixes, and suggest an appropriate metric prefix to use when measuring an object. 2 = you can accurately do two of the requirements 1 = you can accurately do one of the requirements 0 = you are struggling with all things metric and need more teacher help

19. Rate Your Learning on the Learning Goal! 4 = In addition to score 3, you can help teach your peers 3 = you can accurately measure distance, mass, and volume using the metric system. 2 = you can accurately do two of the requirements 1 = you can accurately do one of the requirements 0 = you are struggling with all things metric and need more teacher help

20. The Metric System Let’s talk DISTANCE!

26. Let’s Practice! • Using the metric ruler • “Ruling” Distance Measurement

27. The Metric System Let’s talk MASS!

33. Let’s Practice! • Using the balance • Massive Problems
